Let's convwert 5 + 2/3 to a fraction = 17/3

So we have

17/3 / 1/6         The rule is to "keep" the first fraction, "change" to multiplication  and "flip' the second fraction......So we have

17/3 x 6/1      We can "cancel" the 6 and the 3 and get 2    So we have

17/1 x 2/1  = 34

Remeber when we divide fractions......"keep"  "change" "flip'"

Do you mean 14c = 21 ??   If so, we have

Divide both sides by 14   We have

c = 21/14  = 3/2

If you mean you'd like to factor this, we have

7 (2c - 3)

I don't know if that helps, or not!!

Multiplying the 7 and 4 we get 28

Then multiplying the 7 times x and the 4 times x  and adding them together, we get 11x

And multiplying x times x produces x ²

And putting this together we have

x ² + 11x + 28

And that's it!!

Your calculator probably "overdosed" when it tried to calculate that "1.5" raised to a power greater than 31 million!! You probably got an "error" or "infinite" - or some such thing displayed.

Do you have any particular reason for trying to calculate such a large number??

If so...you might browse around the web......please be advised that trying to find an app that will display ALL the digits of this number is probably fruitless....

Here's a place you might start.....good luck!!

Thanks, alan....I didn't know if it was still in print, or not....I made it about halfway through the book....but I don't have enough math knowledge for some of the rest of it.....The interesting thing to me is that the "chase" for pi seemed to produce some rather interesting things in other areas, too!!

I believe that Melody is correct and we don't even need a graph to prove it.

Note that, in the first quadrant, the tangent is equal to the sine at 0, but at each angle until pi/2, the tangent is greater beause the sine function is being "divided" by 1 whlle the sine function in the tangent is being divided by a cosine function which is less than 1 (but greater than 0).

In quadrant two, the sine is positive and the tangent is negative.

This situation in quadrant 2 is reversed in quadrant 3. The tangent is positive and the sine is negative.  (They are only = at pi.)

In quadrant 4, the situation is reversed from the 1st quadrant...i.e...the sine is a smaller negative than the tangent.

Thus Melody's answer of [0, pi/2) U [pi, 3pi/2) seems good.

Did you get to our site by bypassing that BIG calculator on the entry page??

Try that first........

Use the inverse sine to find the angle opposite the base

You will have sin^-1(base/hyp) = "theta"

Then, just subtract that from 90...that will give you the other angle.

Of course, I'd probably use the Pythag theorem to find the missing side first, too, since a "two-sided" triangle isn't considered kosher.

A = pi * r^2

A = pi * 4^2

A = pi * 16 = 50.27 units²

So dividing 4*10^7 by 5*10^4, we have

(4/5) * (10^7 / 10^4) =

.8  *  10^3 =
